Broken battery door

Might be a stuck switch. Somewhere around the edge of door is a small pressure switch that pops out when door is open and gets pushed back in when door is closed. This can stick or even break.
Check the bulb shoe connectors aren't corroded both on bulb and in socket.
Switch off device first !! then get to bulb and scrape connections with screwdriver tip, very lightly. Switch off first !! (just saying it again).
Test the bulb too with a 9v battery. they may look fine but until you actually know ......

Things to check first for a camera that won't turn on are battery contact points, and micro switches that are located on the battery and memory card doors. Troubleshooting tips on other things that need to be checked may be seen here. These tips won't work for every case, but they're worth a try.

If you have access to the rear of radio, try reversing the channels, to see if the speaker works, and if it does, then you know the wiring to door speaker is ok, if it doesnt, then you know that the wiring is broken somewhere along the route. If you have access to the cable itself only, try using a AA battery, attach the cables to both ends of the battery, and if it makes a noise, then wiring is ok.

How long have you had the camera? If it's less than a year old, then it's under manufacturer's warranty and they need to take it back because there was no customer abuse involved to find it broken...
If it's more than a year old and you have no other warranties on it.. then I'm sorry to say that you might just need to try to fasten something yourself... keep in mind that the only function of that door is to hold the batteries in and to conduct electricity between the batteries... so if you put something there that is also conductive.. then it should be able to work fine.
Just be careful... electricity is sketchy to work with

Try checking these:

- the CD door motor rubber drive belt (if there is one), it could be either loosened or broken, if so, it needs to be replaced

- the door open/closed sensor switches (contacts), they could be oxydized or damaged, they are located somewhere under the CD tray, possibly at the front end of the unit (depends on brand and model), you need to clean these with some fine sandpaper

It could be something else like the door motor driver IC, the power supply for the motor, a bad capacitor in the motor drive section, a loose connection or a broken wire somewhere, but hopefully, it's just a bad rubber belt or a dirty contact.

sounds like you have a shorted wire somewhere.

idk but i would go get another one and it worked fine till i droped it and the touch screen cracked out of site and you have to downlaod the software

mine usually turns on the next day

did you drop it cause this sounds like its been droped
when you droped it the circuitry became jared and broken you need to replace or repair

Unfortunately, Mintek seems to have gone out of business, so there is no way to purchase replacement parts without finding them online somewhere.

The problem could be caused by one of three things:

1. The battery is dead and cannot be recharged
2. One of the battery connections is broken in some way
3. The cord is bad and will not provide power

If the battery is dead, you're stuck with keeping it plugged in or trying to find a battery online. If one of the battery connections is bad, the only way to test it is with a new battery and you're back to finding one online. If the cord is bad, it wouldn't provide power at all, so it sounds like both of your cords are fine.
